Abstract

Cerebral manifestations of Osler-Weber-Rendu disease (OWRD, hereditary haemorrhagic telangiectasia) including telangiectases, venous malformations, and arteriovenous malformations, are usually under-recognised. The highest complication rate is observed in high flow cerebral arteriovenous malformations, which may present with headache, epilepsy, ischaemia, or haemorrhage. Cerebral air embolism during self-contained underwater breathing apparatus (scuba) diving as the first manifestation of pulmonary arteriovenous malformation (PAVM) in OWRD patients has never been reported before. Here we report a 31 year old male who presented desbaric air embolism as the first manifestation of PAVM. As far as we know, this is the first such case published in English medical literature.
